Check Digit Verification of cas no
The CAS Registry Mumber 27685-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,8 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27685-88:
(7*2)+(6*7)+(5*6)+(4*8)+(3*5)+(2*8)+(1*8)=157
157 % 10 = 7
So 27685-88-7 is a valid CAS Registry Number.

Red reactive dye and cotton fiber dyeing method thereof in non-aqueous media
-
Paragraph 0059; 0072-0074, (2019/06/30)
The invention discloses red reactive dye. The structure of the red reactive dye is as shown in formula I, wherein R1 and R2 are independently selected from hydrogen and substituted or non-substitutedC1-C4 alkyl; X is F, Cl or Br; R3 and R4 are independently selected from C1-C4 alkoxy, halogen, hydroxyl and sulfonic group; D1 and D2 are independently selected from substituted phenyl. The red reactive dye has high solubility in non-aqueous media and high affinity to cotton fibers and can dye the cotton fibers in a high dye uptake manner, and corresponding part of hydrolyzed dye which is not fixed to the fibers can be easily washed.
